TIRE--YROTECTOR.

To all whom it may concern:

Be it known that v e, MAfrimw J. Funnnaoi'i and Ariooiyglt/ifCoRniNo'ron, citizens of the United Sta es, residing at Hartley, in the county1 of Orien and State ot' Iowa, have invented certain new and useful linrovements in Tire-Protectors, of which the 'ollowing is a specification.

ln the past it has been proposed to protect the tread or center of the-tire from wear by incasing the tire in a leathern or other inclosure as an auxiliary tread. Harm has frequently resulted from this method as the tire has a marked tendency to heat through the resultant friction and restriction. A potent objection has been the necessarily costly nature of the materials and manufacture ot such casing and which has resulted in making their use expensive and in a great, measure unsatisfactory and prohibitive.

Experience and a full knowledge ol. the conditions have shown that the Wear upon a pneumatic tire comes not upon the tread but upon the side; and especially is this true of 'use upon count-ry roads; and is caused by the continual bulfeting and chat ingv received through contact with the sides of ruts as the tire crushes down into, grinds along through or attei'npts to leave them and also against; the sides of clods, stones, glass, curbs or other obstacles in or along its course.

' In View of the need as heretofore pointed out continuous experiment perfected a dovice of such nature as to overcome the objections heretofore mentioned, and others, While retainino at the saine time such sim plicity of structure and incxpensivencss of material as to reduce its cost ot' productimi to the minimum, obtain the maximum oit efiiciency and place it Well within the reach of the mass of pneumatic and cushion tire users.

A further feature of this invention is the holding togetlienof the two series of shields, guards or boilers installed upon opposite sides of the tire, in such a manner as to allow of no binding on the tire, allowing instead its 'tree action `to alter its position upon the ltire as it does tlirough the action ot' 'the Wheel. in motion upon the ground. For holding the said series of shields, guards or buil'er in place upon the tire side connectors passing over the tread of lthe tire in Specification of Letters Patent.

such direction as to join the opposite series of. shields, guards or bnll'ers are used. lVith these and other objects in view the invention comprisesI certain novel constructions, arrangements, crunbinations and disposals ot' parts as `will hereinafter be more fully described and claimed.

ln the accompanying drawings, .Figure l. is a side elevation ot' part ot'a vehicle Wheel provided with our invention. Fig. is a section on the line 2-2 oi? Fig. l.. Fig. 3

is a plan, enlarged, of one of the` connecting devices. Fig. 4 is a section on the line tui of Fig. 3.

.'Ily referring to the drawings it will be seen that the device consists oi. a series o'l" guards or shields connected together and l0- cated on the side olf the tire, the shield being illustrated in lfig. l, as a plate with lips n turned up thereon at opposite ends, a lip in at the inner edge, and a lip at the outer end of a projection on the opposite edge. These lips are folded over upon the body of the plate and are for the purpose of adding strength thereto, and for providing rounded edges ior presentation to the tire, thus climinatingl injury incident to chaiing. The. wheel rim if; indicattul at o and the tiro at n?, and it will be seen that the protectors are located or extend along opposite sides of the tire ailiordingprotection where it is neeiflod. A t nach end ot the plato is a hole a. to receive the connecting link o by which each section is connected to its neighbor. 'lhe plates are connected over the tread of the tire by i'neans ot a band comprising plates 2' and links li. As shown in Figs. 3 and lf the plates i have their (,dgos and ends bent or 'folded down upon the body of the plate, ivit'h holes to receive the connecting links 7i. which may be made of wire. The connecting links provide the necessary ilexibility for the connections.

The guards or protectors serve to prevent injury to the sides oil the tiro and also to the rim, by contact tlmrewith ol the sides of' ruts, stones, curbs or other road obstructions. As shown in Fig. the ends ot the plates Whore the links join are raised slightly as indicated. at c to enable the links to como flush with the surface ol the tire, with the plates in contact with said surface, and the spaces j' between the ends oi the plates permit oit necessary play or looseness to ac- We claim as *new and desire to secure by Letcommodate variations in the size of the tire.

The folded lips at the edges of the plate ar'- ford rounded surfaces that Will not injure the tire thereunder, and `when placed upon the Wheel the protectors forni rings consisting of a series of connected plates at opposite sides of the tire.

The main' parts of the device may be stamped out of sheet metal or other 1naterial, and when stamp-ed out of sheet metal 'the lips are pressed over to ai'ord the rounded surfaces indicated, and in the movelnent of 'the tire incident to its use no injurions effects result, either fromA the chafing of the tire against the protector or from contact of the tire with curbs or other ob structions, the latter'serving to receive Wear incident to such contact.

Having thus described our invention, 'what ters Patent 'is: A A

l. A tire protector comprising a series of plates, each plate having a lip m at the inner edge thereof, lips 'n at the end thereof, and a projection provided With lips k at the outer edge thereof, all of said lips being folded innooners Wardljvv upon the outer race the plate,I said plates also having openings at each end be- 'tween the lips a, links o extending through `and links connecting the same, each plate having on one side a lateral projection Z with lips /c at the outer end thereof, and cross connections over the tire from the projections of the plates on one side of the tire to those on the opposite side, each of said con-- nections consisting of a series of plates and links, the plates having lips at opposite ends and the linksengaging the plates between said lips.

In testimony whereof, We alix our signatures in presence of two nf'itnesses.
